Gas Gas Tanks / Covers

Do other people have any issues with the tank on the gas gas pro's being soft and easy to dent with their knees?

Does any body know of anywhere that makes / sells covers to protect the tanks? Either carbon fibre or plastic?

If not, I've found a place local to me that might be able to make a carbon fibre cover, I'm trying to gauge interest to see if it would be worth while getting some made and would people be interested in buying them, not sure of a price yet but what would you expect to pay for something like this? Do people think its a good idea? You can get Get covers for just about every other part of the bike, so why not the tank,
